Abstract
The utility model provides a height restriction that high position installed submerged pump is applied to mainly that the fluidic is high -order among the industrial process carries, and the mounting height does not receive liquid level position. The entrance point pipeline of submerged pump inserts liquid level following provisions height, and pump body impeller can be on the liquid level, also can be under the liquid level, and this is the outstanding of this patent, simultaneously, connects gradually the exit end of submerged pump to dashpot, liquid level hoisting device, emptier. At the operation in -process, at first start liquid level hoisting device, make the liquid level working face on the impeller, the restart submerged pump makes pump body normal operating, behind the as ready line stabilization, through pipeline auto -change over device, with liquid conveying to the place that requires. The device has makes the submerged pump mounted position not receive the liquid level restriction, save pump body lift, advantages such as equipment structure is simple, convenient operation.
Description
Technical field
The utility model belongs to the high-order transportation art of liquid, relates to a kind ofly high-orderly installing Under Water Pumps, refers in particular in project reconstruction process, and Under Water Pumps impeller, due to pump shaft length and site environment restriction, uses in the environment making it be installed on liquid level.This patent relates generally to this patent and realizes involved method and apparatus.
Background technique
At present, the installation requirement of Under Water Pumps is mainly on the fixed support that must be vertically mounted on above liquid material pond or tank, and at the bottom of pump intake distance pond, distance is greater than 200mm, and pump housing impeller is in below liquid level, and pump shaft length does not allow long.
Mutual restriction between all installation requirements above, particularly pump shaft length and pump impeller installation requirement, the as installed height limiting Under Water Pumps distance liquid level can not be too high, in the Under Water Pumps industrial application process of large discharge, low lift, especially outstanding.Such as, the old device of current wet phosphoric acid takes the measure of setting up low level flash distillation plant in the mode controlling extractive reaction temperature, often due to the restriction that large discharge axial-flow pump setting height(from bottom) requires, forces extraction tank transform or set up new extraction tank, often invest excessive, increase business burden.
For the drawback that above Under Water Pumps is installed, the utility model runs the angle of basic theory and the impact of pressure change convection cell from the pump housing, work out, with a Under Water Pumps high position, supporting relevant apparatus is installed, have mounting point not by liquid level restriction, saving pump housing lift, the simple advantage of device structure, in industrial storage tank, fluid conveying transformation, application advantage is more outstanding.
Summary of the invention
The purpose of this utility model is the problem that solution Under Water Pumps pump shaft length, pump impeller mounting point and pump housing lift limit setting height(from bottom), provides a kind of high-order installation Under Water Pumps.
The utility model solves the problems of the technologies described above taked technological scheme: a kind of high-order installation Under Water Pumps, comprise Under Water Pumps, dashpot, liquid level lifting device, exhaust gas processing device, it is characterized in that: the entrance point pipeline of Under Water Pumps inserts below liquid level, Under Water Pumps impeller need not be immersed in liquid level, impeller is positioned on liquid level, the outlet of Under Water Pumps is provided with a branch road and is connected to dashpot, another branch road is connected to Liquid transfer destination, dashpot top arranges pipeline and is connected to liquid level lifting device, bottom arranges liquid return pipe road, the outlet of liquid level lifting device is connected to exhaust gas processing device.
Adopt this device the setting height(from bottom) of Under Water Pumps distance liquid level can be improved greatly, the pump impeller mounting point of Under Water Pumps can be made higher than liquid level, greatly save lift simultaneously, have and the more advantages such as convenient, saving energy consumption, equipment are simple to operation are installed, with the obvious advantage in industrial fluids conveying transformation.
Accompanying drawing explanation
Fig. 1 is that the main device that the utility model relates to is equipped with sketch.
Be labeled as in figure: 1. Under Water Pumps, 2. level tank, 3. dashpot, 4. liquid return pipe road, 5. inlet valve, 6. bypass valve, 7. liquid level lifting device, 8. device for recovering tail gas.
Embodiment
According to on-the-spot as installed position, determine Under Water Pumps mounting point, pump impeller is lower than liquid level in principle, when pump impeller setting height(from bottom) is higher than liquid level, under between theoretical pump impeller setting height(from bottom) and conveying liquid levels, definitely the discrepancy in elevation is not more than 10.0m(transfer criteria situation clear water situation)
Under the inlet pipeline of Under Water Pumps being stretched into liquid level during installation >=and 1000mm depths, the outlet of Under Water Pumps is by liquid distributing device, and a branch road is connected to dashpot, and another branch road is connected to Liquid transfer destination.Dashpot top arranges pipeline and is connected to liquid level lifting device, and it is for subsequent use that bottom arranges liquid return pipe road, and liquid is back to liquid level by liquid return pipe road.The outlet of liquid level lifting device is connected to device for recovering tail gas, according to actual conditions, carries out emptying or recycling to tail gas.
In running, first start liquid level lifting device, liquid level be promoted on impeller, when liquid level after promoting be on liquid level and between dashpot entrance time, close dashpot inlet valve by liquid distributing device, start Under Water Pumps, by Liquid transfer to destination; When the liquid level after promoting is higher than dashpot entrance, start Under Water Pumps, liquid is circulated between dashpot, liquid level, close dashpot inlet valve gradually, start bypass valve, by Liquid transfer to destination, after pump housing normal operation, pump housing lift needed for fed distance, determines the operation whether stopping liquid level lifting device.
Using effect of the present utility model the impeller of Under Water Pumps can be installed and more than liquid level, utilize liquid level lifting device, promotes the demand of liquid level reduction to pump housing lift.In industrial fluids conveying transformation process, the advantage of application is fairly obvious, has and installs the more advantages such as convenient, saving energy consumption, equipment are simple to operation.
